This is a new product of the Ichirin-shou (single-flower vase) series. It can also be used as a confectionery vessel to hold smal sweets or bean confectionery called furidashi. It is characterized by the blue color of the Geppaku glaze fired in the Genyo kiln. Three shapes were designed under the theme of roundness. A black lid made of cork and linen is attached to the bowl.
